DETAILED DESCRIPTION

Aspects of the present disclosure are directed toward haptic feedback, and, more specifically, to haptic feedback in networked components. While the present disclosure is not necessarily limited to such applications, various aspects of the present disclosure can be appreciated through a discussion of various examples using this context.

Individuals suffering from the symptoms of old age or diseases such as multiple sclerosis can experience vision loss, hearing loss, and a loss of fine motor skills. These conditions make it difficult for these individuals to use electronic devices. Vision impairments make it difficult for these users to see letters typed on a screen. Additionally, the loss of fine motor skills makes it difficult to use a keyboard and can result in mis-strokes and typographical errors. This results in a need for the user to be able to review what has been typed and make corrections as necessary.

For security reasons, characters inputted into password fields are replaced by masking characters such as, for example, asterisks (e.g., “*”) and bullet points (e.g., “●”). Entering a correct password can be difficult for individuals suffering from deteriorating vision and/or a loss of fine motor skills since there is no opportunity for such individuals to review what has been typed in order to correct any mis-strokes.

One solution involves using audio feedback through the use of a screen reader. This allows the user to receive feedback for what they have typed into a password field. However, the security of the user's personal information is compromised as the password can easily be heard by nearby eavesdroppers

Embodiments of the present disclosure include a computer communicatively coupled to a mobile phone. The computer can receive input through a keyboard. The input can comprise a character (e.g., a letter, a number, a symbol, etc.). The character can have a corresponding character code. The character code can be converted into a corresponding haptic instruction. The corresponding haptic instruction can comprise a plurality of tactile pulses. The plurality of tactile pulses can comprise at least a first pulse lasting a first time and at least a second pulse lasting a second time. The corresponding haptic instruction can be outputted to the mobile phone and cause the mobile phone to activate a haptic motor. The haptic motor can cause the mobile phone to vibrate according to the corresponding haptic instruction. The haptic pattern can be interpreted by a user in order to provide feedback for what is typed.

Aspects of the present disclosure provide numerous advantages. First, aspects of the present disclosure improve usability by allowing the user to receive feedback without requiring the user to visually inspect characters on a screen. Second, aspects of the present disclosure improve information security since the feedback is felt and is not auditory. Thus, users can input personal information (e.g., passwords, social security numbers, etc.) with less risk of the information being intercepted by eavesdroppers. Third, aspects of the present disclosure accelerate feedback. For example, instead of converting large blocks of information (e.g., a paragraph of text) at once, aspects of the present disclosure can convert smaller portions of information (e.g., one character) concurrently while the information is being received (e.g., input, typed, etc.). Thus, aspects of the present disclosure allow a user to receive feedback approximately contemporaneously with inputting respective characters.

The aforementioned advantages are example advantages and not all advantages are listed. Furthermore, embodiments of the present disclosure exist that can contain all, some, or none of the aforementioned advantages while remaining within the spirit and scope of the present disclosure.

Referring now to FIG. 1, illustrated is a block diagram of an example networked components system 100 in accordance with some embodiments of the present disclosure. Networked components system 100 can comprise a first device 110 communicatively coupled to a second device 120 and a server 130. In some embodiments, the first device 110 can be communicatively coupled to the server 130 by a network 140 such as, for example, the internet. The server 130 can include password protected access 132. The first device 110 can have a user interface 112 and an input device 114. Input can be received by the first device 110 through the input device 114. The input received by the first device 110 can comprise a character. The character received by the first device 110 can be transferred from the first device 110 to the second device 120 (e.g., over a personal area network (PAN) 150). The character can be converted to a haptic instruction. The haptic instruction can comprise a plurality of tactile pulses. The plurality of tactile pulses can comprise a first tactile pulse lasting a first time (e.g., 0.1 seconds, 0.25 seconds, 0.5 seconds, etc.) and a second tactile pulse lasting a second time (e.g., 0.3 seconds, 0.75 seconds, 1.5 seconds, etc.). In some embodiments, the second time can last approximately three times the duration of the first time. The second device 120 can vibrate according to the plurality of tactile pulses.

For the purposes of the present disclosure, the second time lasting approximately three times the duration of the first time is understood to be an approximation associated with absolute or relative tolerances. For example, given the first time, a second time within plus or minus 0.1 seconds, 0.25 seconds, or a different amount of time of three times the first time can be considered to be three times the first time. As another example, given the first time, a second time within plus or minus 1%, 5%, 10%, or a different percentage of three times the first time can be considered to be three times the first time.

The server 130 can be, but is not limited to, a website which can have password protected access 132. The user interface 112 can present a password field controlling access to password protected access 132. The password field can comprise a portion of the website hosted on server 130.

The first device 110 can be, but is not limited to, a desktop computer, a laptop, and/or a portable electronic device. In some embodiments, the input device 114 can comprise a physical keyboard. In various embodiments, the user interface 112 can be communicatively coupled to first device 110, or the user interface 112 can be physically integrated within the first device 110.

The second device 120 can be, but is not limited to, a mobile phone. The second device 120 can comprise a haptic motor 124. The haptic motor can be, but is not limited to, an eccentric rotating mass actuator (ERM), a linear resonant actuator (LRA), and/or a piezoelectric actuator.

In some embodiments, the second device 120 can comprise a character database 122. In some embodiments, the character received by the input device 114 can have a corresponding character code. The character code can be, but is not limited to, an American Standard Code for Information Interchange (ASCII) character code, a Unicode character code, and/or an International Organization for Standardization (ISO) character code. Converting the character to haptic feedback can comprise matching the character code to a pattern of pulses stored in the character database 122 and outputting the pattern of pulses as a haptic instruction to the haptic motor 124.

In some embodiments of the present disclosure, the first device 110 is communicatively coupled to the second device 120 by a personal area network (PAN) (e.g., PAN 150). Alternatively, in some embodiments, the first device 110 can be communicatively coupled to the second device 120 by a wireless local area network (WLAN), local area network (LAN), the internet, and/or a hard-wired connection.

In some embodiments of the present disclosure, the second device 120 can comprise a speaker 126 configured to reduce, conceal, cancel, mitigate, or otherwise limit a first acoustic signal generated by the second device 120 as the haptic motor 124 operates. The first acoustic signal can comprise a first amplitude and a first phase. The speaker 126 can produce a second acoustic signal comprising a second amplitude and a second phase. The second amplitude can be equal to the first amplitude, and the second phase can be inverse to the first phase such that the second acoustic signal cancels the first acoustic signal. In embodiments, utilizing speaker 126 to cancel the first acoustic signal generated by the haptic motor 124, information on amplitudes, phases, sequences, durations, and/or other relevant information can be stored in character database 122.

For the purposes of the present disclosure, the first amplitude equal to the second amplitude is understood to mean approximately equal to such that the first amplitude is similar to the second amplitude within a tolerance (e.g., within 1%, 5%, 10%, etc.). Likewise, the first phase inverse to the second phase is understood to mean approximately inverse such that the first phase is inverse to the second phase within a tolerance (e.g., within 1%, 5%, 10%, etc.).

In embodiments utilizing speaker 126 to reduce ancillary noise generated by the haptic motor 124, the character received by the first device 110 can be converted to an instruction comprising a plurality of acoustic pulses and a plurality of tactile pulses. The plurality of acoustic pulses comprising a first acoustic pulse lasting a first time and a second acoustic pulse lasting a second time. The plurality of tactile pulses comprising a first tactile pulse lasting a first time and a second tactile pulse lasting a second time. The plurality of acoustic pulses can then be outputted by the speaker 126 concurrently with the plurality of tactile pulses being outputted by haptic motor 124. The first acoustic pulse can mitigate ancillary noise generated by the haptic motor 124 outputting the first tactile pulse and the second acoustic pulse can mitigate ancillary noise generated by the haptic motor 124 outputting the second tactile pulse. Thus, embodiments utilizing speaker 126 can further improve device security by cancelling any ancillary sounds generated by haptic motor 124 while providing haptic feedback.

In some embodiments of the present disclosure, the speaker 126 can provide aural feedback in lieu of, or in combination with, haptic feedback from the haptic motor. The character received by the first device 110 can be converted to an aural instruction comprising a plurality of acoustic pulses. The plurality of acoustic pulses comprising a first acoustic pulse lasting a first time and a second acoustic pulse lasting a second time. The plurality of acoustic pulses can then be outputted by the speaker 126.

The light source 128 can be, but is not limited to, a light emitting diode (LED), liquid crystal displays (LCD), and LED displays. The character received by the first device 110 can be converted to an instruction comprising a plurality of light pulses. The plurality of light pulses comprising a first light pulse lasting a first time and a second light pulse lasting a second time. The plurality of light pulses can then be outputted by the light source 128.

These computer readable program instructions can also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.

The computer readable program instructions can also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.

The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams can represent a module, segment, or subset of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the blocks can occur out of the order noted in the Figures. For example, two blocks shown in succession can, in fact, be executed substantially concurrently, or the blocks can sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.

While it is understood that the process software (e.g., any of the instructions stored in instructions 560 of FIG. 5 and/or any software configured to perform any subset of the methods described with respect to FIGS. 2-4) can be deployed by manually loading it directly in the client, server, and proxy computers via loading a storage medium such as a CD, DVD, etc., the process software can also be automatically or semi-automatically deployed into a computer system by sending the process software to a central server or a group of central servers. The process software is then downloaded into the client computers that will execute the process software. Alternatively, the process software is sent directly to the client system via e-mail. The process software is then either detached to a directory or loaded into a directory by executing a set of program instructions that detaches the process software into a directory. Another alternative is to send the process software directly to a directory on the client computer hard drive. When there are proxy servers, the process will select the proxy server code, determine on which computers to place the proxy servers' code, transmit the proxy server code, and then install the proxy server code on the proxy computer. The process software will be transmitted to the proxy server, and then it will be stored on the proxy server.

Embodiments of the present invention can also be delivered as part of a service engagement with a client corporation, nonprofit organization, government entity, internal organizational structure, or the like. These embodiments can include configuring a computer system to perform, and deploying software, hardware, and web services that implement, some or all of the methods described herein. These embodiments can also include analyzing the client's operations, creating recommendations responsive to the analysis, building systems that implement subsets of the recommendations, integrating the systems into existing processes and infrastructure, metering use of the systems, allocating expenses to users of the systems, and billing, invoicing (e.g., generating an invoice), or otherwise receiving payment for use of the systems.
